She has never been shy about showing off her stunning figure in TV dramas such as Mildred Pierce and True Blood.

And new stills from controversial HBO series Westworld show Evan Rachel Wood again in a state of undress.

Sitting on a chair as robot host Delores, Evan bares all while being examined by a character played by newcomer Luke Hemsworth - brother of well-established stars Luke and Chris.

The elaborate series is about the android hosts who live in a vast Western theme park, where rich guests pay to act out their every fantasy - including rape and murder - until the robots seem to gain consciousness and seek revenge after a coding malfunction.

The show, which reportedly cost the network an astonishing $100 million and faced multiple production delays, is based on the futuristic 1973 Michael Crichton movie.

Another shot featured the actress posed topless and on a stool with an artfully placed hand protecting her modesty.

HBO finally debuted it's highly-anticipated new pilot Westworld in the U.S. on Sunday with the first episode of the show debuting on Sky Atlantic in the UK on Tuesday.

The new photographs come as Evan defended the show's violent content, urging critics to 'wait for the context.'

She told The Hollywood Reporter: 'It's absolutely very rough. I don't like gratuitous violence against women at all, but I would wait for the context in which it's being used.

'As the show progresses, the way it's being used is very much a commentary and a look at our humanity and why we find these things entertaining and why this is an epidemic, and flipping it on its head,' she added.

'The roles for the women on this show are going to be very revolutionary. It's very gender-neutral.

'I would ask, as somebody who is an advocate against any kind of abuse or violence and is outspoken about it, to give it a chance and wait to see where it's going. I think it will surprise people.'

Westworld also stars Ed Harris as the murderous guest Man In Black, who takes no prisoners and leaves a trail of death and destruction as he tries to access a deeper, even darker, level of the park.

But when a new coding update creates a bug that starts to give the robot hosts the ability to remember their past 'narrative loops' - including what the human guests have done to them - they begin acting out.

Crack programmer Bernard Lowe, played by Jeffery Wright, must try to figure out what's gone wrong and fix the software before someone gets hurt.
